Course Information

Course Description

A comprehensive introduction to basic principles of communication theory with emphasis on analog modulation systems. The topics include: Fourier methods of signal and system representation, amplitude modulation, angle modulation, frequency division multiplexing, super-heterodyning, waveform generation and detection techniques, effects of noise in analog communication systems; analog-to-digital signal conversion, sampling theorem, quantization and pulse code modulation. Prerequisites: Completion of all required second year courses, ELE532 and MTH514.

All course-related information, announcements and material such as lab instruction sheets, pre-lab assignments, hand-outs are available from the BlackBoard.

Course Outline

1. Introduction to Communication Systems: Chapters 1, 2 (sections 2.1-2.4, 2.8, 2.9), and Chapter 3 (sections 3.1-3.6):  Elements of communication systems, Review of signal representations in time and frequency domain,  bandwidth, filters, distortionless transmission (5 hours).
2. Analog to Digital Signal Conversion: Chapter 6 (sections 6.1-6.3): sampling theorem, quantization and pulse code modulation  (4 hours).
3. Amplitude Modulation: Chapter 4 (sections 4.1-4.8) :   suppressed carrier modulation, large carrier modulation, vestigial sideband modulation, single-sideband modulation, super-heterodyne receiver structure, comparison of AM systems, frequency division multiplexing , carrier acquisition (10 hours).
4. Angle Modulation: Chapter 5 (all sections):  Frequency modulation (FM) and phase modulation (PM), narrowband FM, wideband FM, average power in angle modulated waveforms, generation of wideband FM, demodulation of FM signals ( 8 hours).
5. Random Process and Power Spectrum: Chapter 9 (sections 9.1-9.3 and 9.5): Random processes, transmission of a random process through a linear system, energy and power spectral density functions, Gaussian process, correlation functions, narrow-band noise (4 hours)
6.  Effects of Noise in Analog Communication Systems:  Chapter 10 (10.1.-10.3):  Receiver model, noise in DSB-SC receivers, noise in SSB receivers, noise in FM receivers, pre-emphasis and de-emphasis in FM, propagation effects, threshold effect in FM, SNR in AM and FM reception (5 hours).

Note: You are expected to be very familiar with the concepts learned in ELE532: signals and systems. In ELE635, chapters 1 and 2  will be covered on a review basis only. The assigned problems in these chapters (see below) are for you to practice the important concepts in signals and systems.

Course Evaluation

Laboratory Components  (20%)

Lab Performance

15 %

There are five labs. Marks are based on attendance, pre- and post-labs, participation and completion. Pre-lab has to be done by individual student.

Formal Report

 5%

A formally typed lab report should be submitted for one randomly selected lab which will be selected by the TA. Each group will submit only one formal report. The lab report is due in exactly one week from the completion of the lab.

 

Theoretical Components (80%)

Tests

35%

There will be a test which is  worth 35%.
The test is held during the lecture period and it is closed-book with only a non-programmable calculator allowed. Date is on Wednesday, June 13, 10 am - 12 noon.

Final Exam

45%

Final exam is 3-hour in duration. It is a closed book exam with only a non-programmable calculator allowed. It will be held on Wednesday, July 4, 9 am - 12 noon in ENG101.

 

Note: In order to achieve a passing grade in the course, the student must pass both the theoretical and  the laboratory components. All the required reports will be assessed not only on their technical or academic merit, but also on the communication skills of the author as exhibited through the reports.
